Ill try to be quick and to the point. I have a couple of AR lowers purchased before 07/20/2016. They have never been built into a functioning rifle, hence I haven’t EFA10’d them yet. I’d like to SBR them and do a ATF form 1, but do I need to EFA10 them first as a legally 16” rifle, or wait until I do the SBR build after I’m approved (if I ever will be) ?
